While it doesn't come stock in the UJM mold, a C10 can be fitted out to be like one. That's pretty much what I've done with mine.
Kneesaver lowered pegs. Taller, wider bars on a Storz adaptor that extend back more towards the rider than OEM.
If you want more of a bench seat, the pre '94's are like that, or you can have one modded up. I have settled on a Corbin for some time now. It allows me to sit back further away from the tank. Yes its firm (some say hard!) but it works for me.
